In which one of the following points does the induced fit model of enzyme action differ from the lock and key model? *
Substrate bind at the active site of the enzyme
Enzymes lower the energy of activation
During the reaction, an enzyme-substrate complex is formed
The shape of the substrate and active site are not complementary
Answers
Answer:
The correct option is the last option
Explanation:
Firstly, one must understand that the first three options are generally properties of an enzyme and how an enzyme-substrate (ES) complex is formed during a reaction.
Enzymes bind to substrate in two major ways based on the shape of the active site of the enzyme; the lock and key model and the induced fit. The lock and key model is a model in which the active site ordinarily has the shape that can "accommodate"/bind to the substrate directly without any need for any change in the shape of the neither the active site nor the substrate during the process of formation of the enzyme-substrate complex. The induced-fit model is the model in which the active site of the enzyme and/or the substrate undergoes a change in shape as both of them draw close to each other because they ordinarily cannot fit/bind together; the shape of the active site and the substrate are not complementary.
NOTE: The active site is the part of the enzyme in which the substrate binds to.

which innervates a kidney? select all that apply. multiple select question. sympathetic nerve fibers afferent pain fibers somatic motor fibers parasympathetic nerve fibers
Answers
Both the sympathetic and parasympathetic divisions of the autonomic nervous system are responsible for innervating the kidneys.
A highly innervated organ, the kidney. Both afferent and efferent fibers of the renal plexus are involved in kidney innervation. This plexus is made up of fibers that come from the celiac plexus. Each contributing plexus contributes to efferent innervation, which is mostly sympathetic. The kidneys are additionally innervated by parasympathetic fibers from the vagus nerve and fibers from the intermesenteric plexus.
The sympathetic route is followed by afferent fibers that transmit pain from the viscera. The sympathetic trunk is reached by way of the celiac plexus and the splanchnic nerves by the afferent fibers that sense pain coming from kidney stones in the renal pelvis or calyces.

Dna double helices are soluble in water but insoluble in alcohol. How do these physical properties reflect the chemical structure of the dna molecule?.
Answers
The structure of DNA double helices are hydrophilic due to their highly charged phosphate groups and hence are soluble in water.
DNA is highly polar because of its highly charged phosphate backbone. Water is also polar and thus dissolves DNA following the principle " like dissolves like ''. The DNA is composed of N-bases, phosphate backbone, and pentose sugar. N-bases are hydrophobic but are on the inner side of the structure.
Whereas, phosphates are hydrophilic and are on the outer side of the structure. The presence of phosphates outside the DNA structure makes it water-soluble.
In addition to this, H in water is positively charged and phosphates in DNA are negatively charged. This enables DNA to get dissolved in water. On the other hand, alcohol, being polar, reduces the affinity of hydrogen bonds with DNA, thus making it insoluble in alcohol.

define autotrophs and heterotrophs. which are the producers of the ecosystem? which are the consumers? give an example of each group.
Answers
Autotrophs are organisms that can produce their own food from inorganic compounds, such as photosynthetic plants and algae. Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.
In an ecosystem, the producers are the autotrophs, as they form the base of the food chain by producing their own food. The consumers are the heterotrophs, as they rely on the producers or other consumers for food.
Examples of autotrophs include plants and algae, which use energy from the sun to convert carbon dioxide and water into glucose and oxygen through photosynthesis. Examples of heterotrophs include animals such as deer and lions, which consume plants or other animals for energy.
Someone who is active and exercises regularly tends to have a higher metabolic rate than someone who is overweight and lacks exercise. Active people have higher rates of ____ produced by the ____. Group of answer choices Tetraiodothyronine, thyroid gland Thyroid-stimulating hormone, hypothalamus Parathyroid hormone, parathyroid gland Thyroid-stimulating hormone, thyroid gland
Answers
Active individuals who exercise regularly tend to have higher metabolic rates. This increase in metabolic rate is associated with higher levels of tetraiodothyronine (T4), which are produced by the thyroid gland.
The thyroid gland plays a crucial role in regulating metabolism. It produces hormones, including tetraiodothyronine (T4) and triiodothyronine (T3), which are involved in controlling metabolic processes in the body. When someone is active and exercises regularly, their metabolic demands increase.
In response, the hypothalamus releases thyroid-stimulating hormone (TSH), which stimulates the thyroid gland to produce and release more T4 and T3 hormones. These thyroid hormones play a vital role in increasing the metabolic rate of cells throughout the body.
Therefore, in the given options, the most accurate answer is "Tetraiodothyronine (T4), thyroid gland." Active individuals have higher rates of T4 hormone production, which is produced by the thyroid gland and is responsible for regulating metabolism and increasing the metabolic rate.

observe the temperature performance curve below, which shows swimming speed vs. temperature for goldfish (carassius auratus l.). based on the curve, what is the optimal temperature (topt) for a swimming goldfish?
Answers
The optimal temperature for swimming goldfish ideal water temperature for goldfish is 20 to 23 degrees Celsius (68 to 74 degrees Fahrenheit).
Goldfish, in contrast to tropical fish, do not require warm water temperatures to thrive. The Goldfish Tank, a website for owners of goldfish, recommends keeping the water around 23 degrees Celsius. Using a tank heater is the best way to make sure the temperature stays the same no matter how hot or cold the outside gets. Last, the ideal temperature for a swimming goldfish is about 20-25 degrees Celsius. The temperature at which swimming speed is greatest would be the ideal one.
Goldfish thrive in water that is between 73 and 75 degrees Fahrenheit (23 and 24 degrees Celsius) in temperature. Although goldfish can survive in water temperatures up to 30 degrees Celsius, it is recommended that they be kept between those temperatures. Goldfish may be damaged by warmer temperatures.
Despite the fact that goldfish can live in temperatures as high as 30 degrees centigrade, specialists suggest keeping them in water that is somewhere in the range of 23 and 24 degrees.

An insertion mutation usually causes more defects than a point mutation because insertion mutations _____.
Answers
An insertion mutation typically causes more defects than a point mutation because insertion mutations involve the addition of extra nucleotides into the DNA sequence.
This insertion disrupts the reading frame of the gene, leading to significant changes in the subsequent amino acid sequence during protein synthesis. As a result, the protein produced from the mutated gene may have an altered structure or function, potentially leading to more severe consequences.Insertion mutations can have various effects on the protein. They can introduce premature stop codons, resulting in a truncated and non-functional protein. Alternatively, the insertion can shift the entire reading frame downstream, leading to a completely different sequence of amino acids. This disruption often renders the protein non-functional or significantly impairs its normal activity.In contrast, point mutations involve the substitution of a single nucleotide, which may or may not result in a change of amino acid. While point mutations can still have detrimental effects, they are generally less disruptive than insertion mutations, as they do not alter the reading frame or introduce significant changes to the protein structure.For more questions on DNA sequence

What is the top of a hierarchy called?.
Answers
The highest-ranking people are at the apex.
The most common way to represent a hierarchy is as a pyramid, where the width of the level represents how many individuals or business divisions are there in relation to the whole, and the height of the ranking or person depicts their power status.
The highest-ranking individuals are located at the apex and there are typically very few of them, often only one; the base may contain thousands of individuals who have no subordinates.
An organizational chart or organogram is created by using a tree or triangle diagram to represent these hierarchies. Because there are fewer people at the top than at the bottom, those closest to the top have more influence than those closest to the bottom.
As a result, in a hierarchy, superiors typically command and have a greater rank.
